OpenShift on VMware Workstation

Deployment of OpenShift 4.x on VMWare Workstation Pro using the local datacenter option.

The Red Hat sixty (60) day eval license for OpenShift and the customized ISO image with Red Hat Core OS provide a straightforward process to build your lab and lower cost for training.

Requirements:
Local DNS to resolve a minimal of three (3) addresses for OpenShift. (api.[domain], api-int.[domain], *.apps.[domain])
DHCP Server (may use VMware Workstation NAT's DHCP)
Storage (recommend the use of NFS for on-prem deployment/lab) for OpenShift logging/monitoring & any db/dir data to be retained.
SSH Terminal Program w/ SSH Key.
Browsers
Front Loader/Load Balancer (HAProxy)
VMware Workstation Pro 16.x

Specs: (We used more than minimal recommended by OpenShift to prepare for other applications)

Three (3) Control Planes Nodes @ 8 vCPU/16 GB RAM/100 GB HDD with "Red Hat Enterprise Linux 8 x64 bit" Guest OS Type
Four (4) Worker Nodes @ 4 vCPU/16 GB RAM/100 GB HDD with "Red Hat Enterprise Linux 8 x64" Guest OS Type

Post-Efforts: Apply these to provide additional value. [Included as examples]

Add entropy service (haveged) to all nodes/pods to increase performance.
Let'sEncrypt wild card certs for *.[DOMAIN] and *.apps.[DOMAIN] to avoid self-signed certs for external UIs. Avoid using "thisisunsafe" within Chrome browser to access the local OpenShift console
Update OpenShift Ingress to be aware of more than two (2) worker nodes.
Update OpenShift to use NFS as default storage.
